Orbital dependent magnetic exchange interaction in CeX (X=S, Se, Te)
Takeshi Matsumura, Akira Ochiai
Dispersion relations of the crystal-field excitations in cubic antiferromagnets CeTe, CeSe, and CeS have been investigated by inelastic neutron scattering using single crystalline…
Helical Ordering of Spin Trimers in a Distorted Kagome Lattice of GdRuAl Studied by Resonant X-ray Diffraction
Takeshi Matsumura, Yusaku Ozono, Shintaro Nakamura +2
Successive magnetic phase transitions at =17.5 K and =18.5 K in GdRuAl, with a distorted kagome lattice of Gd ions, is studied using resonant X-ray diffrac…
Kondo effect in CeX (X=S, Se, Te) studied by electrical resistivity under high pressure
Y. Hayashi, S. Takai, T. Matsumura +5
We have measured the electrical resistivity of cerium monochalcogenices, CeS, CeSe, and CeTe, under high pressures up to 8 GPa. Pressure dependences of the antiferromagnetic orderi…
Specific heat of segmented Heisenberg quantum spin chains in (Yb_{1-x}Lu_x)_4As_3
R. Matysiak, P. Gegenwart, A. Ochiai +3
We report low-temperature specific heat, , measurements on (YbLu)As with and , where nonmagnetic Lu atoms are randomly distributed on ant…
Singlet-triplet Crossover in the Two-dimensional Dimer Spin System YbAl3C3
Shunichiro Kittaka, Tomoyoshi Sugiyama, Yasuyuki Shimura +3
Low-temperature magnetization (M) measurements down to 0.1 K have been performed in magnetic fields up to 14.5 T for a single piece of a tiny single-crystalline sample (0.2 mg weig…
Unified understanding of the valence transition in the rare-earth monochalcogenides under pressure
Ignace Jarrige, Hitoshi Yamaoka, Jean-Pascal Rueff +10
Valence instability is a key ingredient of the unusual properties of f electron materials, yet a clear understanding is lacking as it involves a complex interplay between f electro…
